摘要： PURPOSE:To provide wt. reduction and high speed printing operation and to obtain excellent durability by enhancing hardness and reducing abrasion, by forming a printing wire by processing a sintered body of doped molybdenum containing one or more kind of aluminum, silicon and potassium. CONSTITUTION:A printing wire is formed by processing a sintered body of doped molybdenum containing one or more kind of aluminum (Al), silicon (Si) and potassium (K) and, if surface reducing processing is applied to the sintered body comprising the doped molybdenum, a high hardness product can be obtained by the actions of Al, Si and K. The compositional range of Al. Si and K is set to 0.005-0.75% on a wt. basis and, if the contents thereof are too little, effect is reduced and, if too much, the surface reducing processing is difficult. The doped molybdenum powder having one kind or plural kinds of Al, Si and K added thereto in a predetermined ratio is pressed to mold a compacted powder which is, in turn, sintered to obtain the rod-shaped sintered body. Next, rolling processing and wire drawing processing are applied to the sintered body to form a wire material which is, in turn, cut into a predetermined length to form the printing wire.

摘要： PURPOSE:To provide a light wt. printing wire having high strength, by forming said printing wire from a sintered alloy wherein rhenium is added to a high m.p. metal. CONSTITUTION:A high m.p. metal forming a printing wire is tungsten (W) and molybdenum (Mo) and rhenium is added to said metal in a wt. ratio of 1-35%. If the addition ratio thereof is 35% or more, material cost becomes high and the processability of the obtained alloy is lowered because the hardness thereof becomes high. The printing wire is prepared by applying rolling processing and wire drawing processing to a sintered bar formed by sintering a compacted powder comprising a tungsten-rhenium powder mixture of a molybdenum-rhenium powder mixture to form a wire material and cutting said wire material. The working ratio to the sintered bar is set to 98% or more. If the sintered bar is processed at this high working ratio, the structure of the printing wire can be developed sufficiently into a fibrous state and the printing wire sufficiently developing the excellent strength characteristic possessed by the tungsten-rhenium alloy and the molybdenum-rhenium alloy can be manufactured.

摘要： PURPOSE: To provide the titled junction electrode capable of preventing the oxidation without cooling the electrode, by joining a glass-smelting part made of Mo and a holding part made of a heat-resisting alloy having oxidation resistance.
CONSTITUTION: The objective glass smelting junction electrode is manufactured by joining the glass smelting part 1 made of a round Mo rod and the holding part 2 made of a round rod of a heat-resisting alloy (e.g. Fe-Al-Cr alloy) resistance to oxidation. The glass smelting part 1 is inserted to the inside of the furnace wall 6, and the holding part 2 is fixed to the furnace wall 6 with the holder case 3. The base of the holding part 2 is connected to an electrical source to energize the junction electrode. The glass in the furnace is molten by the electrical current applied from the glass smelting part 1. Since the oxidation can be prevented by the use of the above electrode without cooling the electrode exposed to air, the electrode-cooling apparatus can be omitted resulting in remarkable reduction of the initial cost, and molten glass having uniform quality can be produced. Furthermore, the cost of electrode can be reduced because expensive Mo is used only to a part of the electrode.

摘要翻译：目的：提供能够防止氧化而不冷却电极的标称接合电极，通过接合由Mo制成的玻璃熔融部件和由具有抗氧化性的耐热合金制成的保持部件。构成：目标玻璃熔融接合电极通过将由圆形Mo棒制成的玻璃熔炼部分1和由耐热合金（例如Fe-Al-Cr合金）的圆棒制成的保持部分2接合而制造，氧化。将玻璃熔融部1插入炉壁6的内部，将保持部2用保持器壳体3固定在炉壁6上。保持部2的基部与电源连接，接电极。炉内的玻璃被从玻璃熔炼部分1施加的电流熔化。由于可以通过使用上述电极来防止氧化，而不会使暴露于空气的电极冷却，可以省略电极冷却装置，从而导致可以显着降低初始成本，并且可以产生具有均匀质量的熔融玻璃。此外，由于昂贵的Mo仅用于电极的一部分，所以可以降低电极的成本。

摘要： PURPOSE: To obtain an Mo jig for a high-temp. heat treatment having excellent high-temp. strength by subjecting a doped Mo material subjected to reduction working at a prescribed reduction ratio or above to stress relief annealing at the recrystallization temp. or below then forming the material and subjecting the formed material to a heat treatment at the temp. higher than the recrystallization temp.
CONSTITUTION: A doped Mo sintered material contg. 0.005W0.75wt% ≥1 kind among Al, Si and K is subjected to hot rolling at a reduction rate of ≥85%. The resulting doped Mo material is subjected to strain relief annealing as it is or at the recrystallization temp. or below and is then formed to a boat for heat treatment. Said boat is then heat-treated in a temp. range from the temp. higher by 100°C than the recrystallization temp. up to 2,200°C. The Mo jig for high- temp. heat treatment having improved resistance to thermal fatigue and creep strength is thus obtd. The Mo jig is usable in a stable state for a long time at elevated temp. and contributes to a considerable improvement in the operating efficiency and reliability of a ceramic calcining furnace and a high-temp. heat treating furnace, etc.
